I could only answer 14. and it is 138.3
First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2
Now, this is the answer for angles between 0 and 2pi
but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:
x = pi/2 + n*pi
here n is any integer.
Answer:
Step-by-step explanation:
there are more money during the week 1 because having a -$8 balance is better than having a -$10 balance, -8 > -10
week 2 has a greater absolute value
| -10| = 10 and |-8| =8 and becasue 10> 8 then |-10| > |-8|
Substitute the value of b = -2 to the expression
